A 200 GHz fixed tuned balanced frequency doubler using suspended membrane technology and integrated diodes is described. The design is discussed with reference to DC and RF circuit losses, integrated diode-membrane structure and ease of construction. Finite element analysis and harmonic balance methods were used to optimise multiplier performance. Predictions show peak power output of 15 mW and peak efficiency of 12% at 200 GHz. Key device fabrication steps are also described.
